weighting function

Residual Variability

weighting is a secondary function called during estimation run to evaluate the model(s) of residual variability specified by the code provided in the $VARIANCE block. weighting is typically not called directly by users.

weighting(parms = NULL,
            derparms = NULL,
            codevar=NULL,
            y=NULL,
            xdata=NULL,
            check=FALSE)

Arguments

• parms: A vector of primary parameters.
• derparms: A list of derived parameters, specified in the $DERIVED block of code.
• codevar: The content of the R code specified within the $VARIANCE block in the model file.
• y: The matrix of structural model predictions.
• xdata: A vector of times at which the system is being evaluated.
• check: An indicator whether checks should be performed to validate function inputs

Returns

Return a matrix of numeric values of the same dimension as f.
